of your ZyXEL omni.net ISDN TA.
Configuring ISDN Parameters
ISDN Parameter
Outgoing Protocol
Control
Description
Sets the calling protocol for the your ZyXEL omni.net ISDN TA. The
protocol selected should match the protocol in use by the device or
network your ISDN TA is calling. Selections are
[X.75/V.110/V.120/PPP].
Note: PPP is the most widely used protocol for Internet Access.
Multilink
$ Check the selection box if you want to combine 2 x B-channels to
increase the data transfer rate. This is called multilink.
Multiple Link
% Multiple Link with two independent B-Channels.
STAC or V.42bis
Compression
You can enable or disable data compression by checking or
unchecking the check box.
Data Rate
Click the 56Kbps or 64Kbps option button.
Call Bumping
Call Bumping configures your ISDN device to allow outgoing or
incoming analog calls while a Multilink connection is established.
If this box is checked when a handset is picked up on a POTS port, or
an incoming analog call is detected, the B-channel associated with this
call will disconnect from the ISDN data call and allow the analog call to
proceed.
Keep Connection Alive
Keep Connection Alive sets a timer that will send a dummy PPP
packet every 59 seconds to maintain the connection with the remote
device.
This is useful during long periods when there is no data transfer, but
you do not wish to be automatically disconnected by the remote
device.
Note: Do not set this option if you are charged by time usage, as this
can maintain the connection indefinitely until it is manually
disconnected.
Bandwidth-On- Demand
Bandwidth-On-Demand settings are used to control the adding and
removing of the 2nd link of a Multilink connection.

Chapter 4
ISDN Communication Basics
This chapter covers how to initiate and receive calls over digital lines using your ZyXEL omni.net
ISDN TA.
Understanding AT Commands
AT commands are used to configure and control the omni.net by typing the command statements at
the computer or terminal keyboard. Command statements must be written in a specific form in
order for the omni.net to recognize them. A command statement begins with the letters string [AT]
or [at], followed by one or more alphanumeric commands (a set of letters and numbers) and then
ended by pressing <Enter>, as shown in the following examples.
Examples of AT Commands
Type
AT Command

Response
Operation
To verify that the omni.net is
online with your terminal or
computer.
To inquire about the current
setting of the packet length or
frame size.
OK
Maximum user data length in packet:
Table 19. Examples of AT Commands
AT commands can only be issued when the omni.net is in command or off-line mode.
Once the omni.net has established a connection with the remote device, it goes into on-line mode,
4-1
Technical Reference for ZyXEL omni.net series
and the characters sent from your computer (through the TA) are transmitted to the remote device.
In order to issue an AT command statement, you first need to run your communications software
and configure it to the port connected to your omni.net. (Refer to your communications software
manual.)
Additional AT Command Set for Internal Fax/Modem (for ZyXEL
omni.net LCD+M only)
Beside the AT commands supported by omni.net LCD, there are additional AT commands for
internal fax/modem usage to control speaker (ATMn and ATLn), data compression (AT&Kn),
modem dial out (ATDMs), fax command set (EIA Class 1 fax commands), etc.

Table 20. Supported AT Command Types
Quick Tips when Issuing AT Commands
!
To execute an AT command, press the <ENTER> or <RETURN> key.
!
Multiple AT commands can be combined into one line by using the [AT&] function. For
example, [AT&O2] and [ATB02] can be combined into one line [AT&O2B02].
!
The TA executes commands from left to right. The AT command that appears to the right
might over-write the command to the left. For example, [ATB13B14] will result in
[ATB14] since both [B13] and [B14] can not co-exist.
!
If you see duplicated characters for each one you type, your omni.net and software both
have their echo feature turned on (the omni.net default setting enables command echo).
To eliminate the double characters, turn off software command echo.
!
To repeat the last command, type [A/]. (No AT prefix is needed for this command.)
!
The omni.net supports either verbose result code (i.e. OK) or numerical result code (i.e.
0). You can use [ATVn] command to set it one way or the other:

Select numerical result code

Technical Reference for ZyXEL omni.net series
Outgoing Calls
After you have connected your omni.net to the ISDN line, your computer, and analog phone
(omi.net LCD/Plus only), then you are able to place outgoing data and voice calls.
Dialing Data Calls
You can use the command [ATDI] to instruct your omni.net to make an ISDN data call.
& Type: ATDI17142630398<enter> (Make a Data call)
Dial Out Voice Calls (for ZyXEL omni.net LCD/LCD+M//Plus)
You can use your analog phone connected to Phone port 1 and 2 to dial out directly, or choose to
type the command [ATDA], [ATDB] to instruct your omni.net that you wish to place an ISDN
voice call. Command [ATDA] switches the call to analog port 1, while [ ATDB] assigns the call to
analog port 2.
& Type: ATDA17146930762<enter> (Make a voice call on analog port 1)
Dialing Out using internal Fax/modem (for ZyXEL omni.net
LCD+M)
Using the “M” command following the “ATD” will tell your omni.net LCD+M to automatically
switch calls to the internal fax/modem once dialing is complete.

The manual switching functions will only be necessary if your communication software does not
allow you to change your dial-up string.
Conventional dialing commands [ATD], [ATDT] and [ATDP], used by much existing
communication software, can be mapped onto one of the new dialing commands according to the
[AT&O] setting, as follows:

Placing a Data Call
While placing a voice call can be as simple as dialing out with your analog phone, initiating a data
call requires prior selection of a proper B-channel protocol. Here are some simple commands that
will be useful when placing a call. The omni.net has the capability to automatically detect the
B-channel protocol (V.120, X.75, or PPP) used by the answer site.
AT Command
Description
ATBnn
Changes ISDN B channel protocol setting.
ATDL
Re-dials the last dialed telephone number.
Table 24. AT Command for Placing a Data Call
Multi-Auto Dial Out (MDO) for Outgoing Data Calls
With the Multi-Auto Dial Out function, your omni.net automatically tries the outgoing data
protocol with the predefined protocol sequence set by the commands [ATB90-97], as listed in the
following table.
AT Command
MDO Protocol Trial Sequence
ATB90
PPP+X.75
ATB91

Note: Bundle call is not supported in MDO X.75+V.120+PPP
Table 25. MDO AT Command
Incoming Calls
This chapter provides guidelines for setting up the your omni.net to answer calls.
4-7
Technical Reference for ZyXEL omni.net series
The ZyXEL Multi-Auto feature allows your omni.net to automatically detect calls, to identify calls
as analog or digital and to route them accordingly.
When an analog call comes in, the omni.net sends the call to the analog port as the factory default,
Phone 1 and then Phone 2 (for omni.net LCD/ LCD+M/Plus).
When a data call comes in, the omni.net automatically detects the PPP, V.110, V.120, and X.75
protocols, and negotiates a connection using the proper B-channel protocol, thereby freeing users
from manual protocol configuration.
Answering a Call Using MSN
When answering an incoming call, the omni.net will first be identified if the calling number
matches the MSN settings.
The Multiple Subscriber Number (MSN) supplementary service enables multiple ISDN numbers to
be assigned to a single ISDN BRI line. It allows the caller to select, via the public network, one or
more distinct terminals from a variety of terminal choices. Since the omni.net supports many
different communication protocols and two analog adapters, each of these ports can individually be
assigned to a different ISDN number using the following [AT&ZIn=s] AT command:
AT&Zin=s (where 's' is the MSN)
&ZI0=s
Assigns MSN 's', phone number for X.75
&ZI1=s
Assigns MSN 's', phone number for V.110
&ZI2=s
Assigns MSN 's', phone number for V.120
&ZI3=s
Assigns MSN 's', phone number for PPP, MPPP
&ZI4=s
Assigns MSN 's' for ISDN data, protocol auto-detection
&ZI6=s
Assigns MSN 's', phone number for Phone 2 (for omni.net LCD/Plus) and modem (for
omni.net LCD+M only)
&ZI7=s
Assigns MSN 's', phone number for Phone 1 (for omni.net LCD/ LCD+M/Plus)
Table 26. AT Command for answering a call using MSN
[AT&ZI?] can be used to display the MSN numbers. The factory default for these numbers are
UNASSIGNED.
4-8
Technical Reference for ZyXEL omni.net series
If an incoming SETUP message is offered with addressing information (i.e. the appropriate part of
the called_party_number), this address will be compared with the MSN numbers assigned by the
[AT&ZIn=s] commands. The call will be accepted using the specific protocol, if the assigned
number of this protocol matches the received called party number.
NOTE: You are not required to enter the complete number string for
the [AT&Zin] command. The last few distinguishable digits will be
enough for the Omni.net to make the decision. Two phone number
strings are said to be matched if their least significant 'n' digit(s) are
identical, where 'n' is the number of digits in the shorter string.
Called_Party_Subaddress information within the incoming SETUP message can also be used to
select the protocols and/or analog ports. In normal conditions Called_Party_Subaddress
information is not used by the omni.net to select the protocols or services, but only indicates the
subaddress (if any) to the DTE.
4-9
Technical Reference for ZyXEL omni.net series
Data Over Speech Channel (for ZyXEL omni.net
LCD/LCD+M/Plus)
If you are expecting ISDN data calls through the Speech (Voice) channel, you need to setup MSN
for that purpose. To the omni.net, if no MSN entries are found in MSN ISDN data lists, all Speech
(Voice) calls will be sent to either Phone 1 or Phone 2. Which entry to use would depend on the
type of data call that you are expecting. If you only expect PPP calls, you should enter the number
that the remote user will use to dial in: entry #3 [AT&ZI3=xxx]. Once this is set, the omni.net will
attempt to use PPP protocol to handshake with the remote site whenever a caller dials into this
number.
Best-effort Call Answering (for ZyXEL omni.net
LCD/LCD+M/Plus)
If some numbers have been set using the &ZIn command (this can be seen by issuing the [AT&ZI?
Command] and they are not matched with the address of the incoming call, the omni.net will, by
default, ignore the call as it may be intended for other devices that share the same S/T interface (S/T
bus) with the ISDN TA.
If you want the omni.net to answer inbound calls using all possible protocols, you can set the
best-effort call answering bit as follows:
Command
Description
ATS119.3=0
Answer call only when number matched (default)
ATS119.3=1
Best effort call answering
Table 27. AT Commands for Best-effort Call Answering
Ambiguity Resolution Switch for Voice Calls (for omni.net
LCD/LCD+M/Plus)
Voice calls are routed to one or both of the POTS ports (Phone 1 or/and Phone 2) when they are
received. /and Phone 2) when they are received. You can choose the POTS port you want to receive
calls by setting the MSN (command [AT&Zin=s], as described in a previous table) to a specific
4-10
Technical Reference for ZyXEL omni.net series
phone number 's'.
In cases when the omni.net is unable to distinguish which POTS port to route the incoming voice
call to, your ISDN TA will alert both POTS ports by default [ATS120.2=0], until the first
available port answers. Otherwise [ATS120.2=0], an ambiguity resolution bit (Bit 5 of S84, or
&Ln) can be used to determine the path.

A global call is an inbound voice call with no destination phone number (Called-Party-Number)
which may happen on some switches when the calling site is on the PSTN (analog telephone). By
default, the omni.net will route the global call to both the POTS ports (making them alert). The
phone port that picks up the phone earlier answers the call.

Three Way Conferencing
The three way conferencing feature allows you to add another party to an existing call, and gives
you additional flexibility in selecting which call to drop at closure.
You first need to subscribe this service from your telephone company. Then, issue the command
[ATS120.7=1&W0Z0] that will assign the Flash key to supplementary service.
In addition, and for USA only, request the IOC (ISDN Ordering Code) from your telephone
company. The IOC is used by your omni.net TA as feature access code to conference calls (The
IOC should range between 0 and 63.) Save the IOC to the omni.net TA by typing the following
command: AT&ZF1=IOC-of-CONFERENCE
Starting a conference call
If you wish to call another party C and let them join in to conference with an existing call, follow
these steps:
Step 1. Press the flash key and immediately release to put the existing caller B on hold and
receive a dial tone.
Step 2. Dial to third party C that you want to invite in your conversation.
Step 3. After party C answers, press the flash key and immediately release to establish a
three way conference call.
NOTE: If you wish to cancel your attempt to establish a conference
call (third party line is busy or if they do not answer), simply hang-up
the phone and pick it back up after it starts ringing to return to the first
caller.

Point-To-Point Protocol (PPP) is designed for simple links, which transport packets between two
peers. These links provide full-duplex simultaneous bi-directional operation, and are assumed to
deliver packets in order. PPP is intended to provide a common solution for easy connection for a
wide variety of hosts, bridges and routers.
In the process of configuring, maintaining and terminating the point-to-point link, PPP goes
through several distinct phases, as specified in the following simplified state diagram:

Data will be transmitted only when the link is in the open phase. Negotiation details are described in
RFC1661.
Feature List
Async to Sync Conversion
PPP uses HDLC-like framing as encapsulation, which can be bit-oriented or character-oriented.
Most ISDN routers use bit-oriented HDLC framing, also known as synchronous transmission.
However, serial transmission in most personal computers is still character-oriented, also known as
asynchronous transmission. In order for an ISDN router and PC to communicate, it is necessary to
do asynchronous to synchronous conversion. The omni.net can be used as a bridge. Any data from
a PC to a ZyXEL Omni TA will be converted from asynchronous to synchronous form and vice
versa.
PPP HDLC framing is described in RFC1662. PPP over ISDN is described in RFC1618.

Authentication Conversion
After a link is established, it is necessary to authenticate the peer for security reasons. There are two
popular authentication methods. One is Password Authentication Protocol (PAP) and the other is
Challenge Handshake Authentication Protocol (CHAP). PAP is less secure because it transmits the
username/password in plain text form. Unlike PAP, CHAP transmits the username/password in
coded form. Some ISPs may support CHAP as the only method for authentication.
For those applications that do not support CHAP, the omni.net converts PAP into CHAP. By
default, the PAP/CHAP conversion is always activated, so the authentication from the ISDN TA to
PC is always PAP. That means you must configure your software to accept plain text as password
authentication. Do not worry about password leakage, the omni.net TA will send the password out
7-2
Technical Reference for ZyXEL omni.net series
in hashed form by CHAP. Sometimes CHAP can not be supported by the ISP. You may set
[S87.2=1] to use PAP only. If you do not want to do authentication at all, set [S118.3=1] to
disable the conversion.
CHAP is described in RFC1994 and PAP is described in RFC1334. The only hash method
supported by CHAP is MD5; MS-CHAP is not supported yet. Presently, authentication conversion
works for clients only.
NOTE: Disabling authentication may cause problems in Windows
95.

Table 36. Authentication AT Commands
Compression Control Protocol (CCP)
The ISDN channel can be utilized more effectively when using compression. Compression Control
Protocol (CCP) is used by PPP to negotiate compression methods between peers.
CCP starts after the PPP reaches the network phase. Both ends must support the same compression
method to start packet compression. ZyXEL omni.net supports STAC/LZS. Right now STAC/LZS
is only supported with single history check mode 0 (none), 3 (sequence) and 4 (extended). Mode 1
(LCB) and mode 2 (CRC) are not supported due to patent limitations. CCP negotiation is described
in RFC1962. STAC/LZS is described in RFC1974.
The omni.net will monitor the DTE activity. If software compression has been negotiated, the
ISDN TA will automatically disable STAC/LZS compression.

Table 37. Compression Control AT Commands
Multilink PPP
There are two B channels in basic rate ISDN. This offers the possibility of opening multiple
simultaneous channels between systems giving users additional bandwidth on demand. Multilink
PPP is a method for bundling both B-channels into one PPP link for higher throughput.
Multilink PPP must be negotiated in the establish-link phase by both peers. If the negotiation is
successful, the second link will be dialed after the first link reaches network phase. In some
countries the directory number is not the same for both channels. For dialing the second B-channel
with a different directory number, both numbers must be obtained before dialing out unless the peer
supports BACP/BAP, which will be described later in this chapter. Multilink PPP is described in
RFC1990.
CCP AT Commands
Description
AT&J3
Enable Multilink PPP.
ATDI<num1>[+<num2>]
Dial Multilink PPP with num1 twice or with num1 and num2 if they differ.
ATS61.3 = 0
Use rotate method to bundle both channels (default).
ATS61.3 = 1
Use split method to bundle both channels.
Table 38. CCP AT Commands
Call Bumping
You can place or answer a voice call from a device that is attached to one of the POTS ports while
Multilink PPP is active. The omni.net automatically drops one of the channels and assigns it to
voice calls. Once a voice-call ends, the omni.net automatically re-establishes the channel.
When fully disconnecting with the central switch, there is a 10-seconds time delay between
on-hook phone and channel re-establishment. During call bumping, the traffic for BOD is still
7-4
Technical Reference for ZyXEL omni.net series
under calculation. In other words, the add/persist time is calculated from the time when the traffic is
above the add-threshold whether or not the phone is on-hook or off-hook. However, it will not dial
until the phone has been on-hook for 10 seconds.
Call bumping works for both client (dialing) side and server (answering) side. However, the
channel re-establishment is only effective on the client side.

Technical Reference for ZyXEL omni.net series
Bandwidth On Demand (BOD)
The function of Bandwidth On Demand (BOD) will monitor the traffic on ISDN links while in
Multilink PPP mode. If there is light traffic on the link, one of the channels will be dropped
automatically. On the other hand, if only one B-channel is used and data traffic is high enough,
BOD will establish the second B-channel to increase the bandwidth of the data link.
The wait for the second B-channel carrier is 60 seconds. If the second B channel can not be
connected successfully the BOD will try again after 60 seconds. If the second call is connected but
negotiation failed, the omni.net will retry three times. If a connection is still not established after the
third try, the Multilink PPP will be disabled automatically.
For BOD, there are four parameters to set high/low threshold and persist time. Traffic utilization is
measured in the ISDN link. Highly compressible data may not generate enough traffic to start the
second B-channel. Both add-persist time and subtract-persist time must be set to activate BOD.
BOD AT Commands

minutes.
Table 40. BOD AT Commands
BACP/BAP
Bandwidth Allocation Control Protocol (BACP) and Bandwidth Allocation Protocol (BAP) is used
for call request and link drop under Multilink PPP.
BACP is negotiated during the network phase. Without BACP/BAP, the directory numbers of both
B-channels must be specified before dialing out. In some cases, it is not possible for the ISP to
support more than one chassis that is capable of bundling both channels at the same time. With
BACP/BAP, the second B-channel directory number can be obtained while requesting a call.
7-6
Technical Reference for ZyXEL omni.net series
The second directory number is not necessary any more. The BACP/BAP is supported on the client
side only, and the server side of BACP/BAP will be implemented in an upcoming release.

Description
V.110
V.110 is most popular in Japan.
V.120
V.120 is most commonly used in the U.S.A.
X.75
X.75 was originally designed for packet-switched signaling systems in public networks
to provide data transmission services. However, it is now also used as the link layer for
telematic services (as defined in T.90) in ISDN. These services include both ISDN
circuit-switched mode (DTE-DTE communication) and ISDN packet-switched mode
(DTE-DCE communication).
Table 43. Description of V.110, V.120 and X.75 ISDN Protocols
Answering V.110, V.120, and X.75 Calls
In most cases, there is no need to configure the ISDN mode to the protocol of an incoming call.
Your omni.net is able to determine the correct protocol to use by examining the data coming in
from the remote site if the device is set to auto-answer or once an answer command is issued.
To allow your ISDN TA to auto-answer the incoming call, you need to set [S0] to a value greater
than or equal to 1 (i.e. ATS0 1). If [S0] is not set (S0=0), the DCE will report "RING" to your
terminal, and also make an audible ring notification.
Placing V.110, V.120, and X.75 Outgoing Calls
The following tables describe the [ATB] commands used to specify the outgoing protocol.

Technical Reference for ZyXEL omni.net series
V.120 Outgoing Protocol
Some switches transmit all network signals through the D-channel (out-of-band signaling), allowing both
B-channels to be used exclusively for your communication purposes. This allows for throughput of 64Kbps per
channel. However, not all switches support out-of-band signaling at this time. For switches that do not support
out-of-band signaling, network signals are transmitted through the B-channels. This reduces the bandwidth to
56Kbps.
When you are making a V.120 call, make sure that the communication supports out-of-band signaling. If it
does not support out-of-band signaling, you will need to set your omni.net to 56K mode using the [AT&E1]
command ([AT&E0] to set it back to 64k mode.) If your ISDN TA is on the receiving end, you can keep the
setting at AT&E0, 64k data mode. The omni.net will automatically switch between the two speeds in answer
mode.

Now you are ready to dial the phone number. If you need to save the setting into non-volatile RAM, issue the
following commands:
AT&W0<Enter>
Save the settings to profile 0
OK
[Profiles available: 0-3]
ATZ0<Enter>

All the above commands can be simplified by combining all of the commands onto one line as follows:
&
AT&B20&E1&WZ0<Enter>
Finally, use the [ATDIn] command to make the call ('n' is the phone number you wish to dial). Once the
connection is made, you should see the following connect message.
ATDIn
CONNECT 115200/V120 56000/LAPD
This indicates that the connection is made with:
) DTE speed of 115,200bps.

X.75 Outgoing Protocol
The X.75 protocol can be chosen using the following AT commands:
AT Command
Description
ATB00
X.75 with transparent layer 3.
ATB01
X.75 with T.70 NL.
The ATB0x commands not only specify the outgoing protocol, but also set the default layer 3 for an incoming
X.75 call without layer 3 information. It is important for both ends of an X.75 connection to execute the same
pre-assigned layer 3 protocol, as it reduces the chance that the ISDN TA will make the wrong protocol
selection.
For European ISDN (DSS1), the Low-Layer-Compatibility (LLC) information element in the SETUP message
can be used to specify the layer 3 protocol. Since this is an option for ISDN switches, some of the switches
might not deliver the LLC information element to the remote end.

Synchronous Connections (for omni.net LCD/LCD+M)
The ZyXEL omni.net LCD/LCD+M has synchronous mode included for transfering the data
synchronously. Use the following commands to choose the data rate for synchronous operation:
AT Command

Table 47. AT Command for Synchronous Connections
There are two modes of synchronous operation:
Asynchronous commands, synchronous data (AT&M1): The omni.net LCD/LCD+M accepts
AT commands in asynchronous mode. Once the call is connected, it enters synchronous mode for
data transmission.
Synchronous mode (AT&M3*I1): The omni.net LCD/LCD+M accepts synchronous commands
from V.25 bis or a PC with an add-on synchronous card, and exchanges data synchronously with a
remote TA. (For more information on Async to Sync conversion, please refer to Chater 7.)
8-5
Technical Reference for ZyXEL omni.net series
NOTE: The omni.net LCD/LCD+M does not support network
independent clock compensation. The synchronous timing source
must be supplied by the omni.net LCD/LCD+M , which is phase
locked to the network synchronous clock.
When in V.25bis command mode, the omni.net LCD/LCD+M supports the bit-oriented HDLC
(High-Level Link Control) synchronous protocol which most synchronous communication links
use. Use AT*Ii to enable V.25bis commands. For synchronous applications the TA is set for use
with one application, in normal situations. Save the desired settings in the power-on profile and the
TA will start up in synchronous mode with V.25bis enabled. A special command set RST is
provided to get the TA back to asynchronous AT command mode from V.25bis mode.
When the TA is used as a DCE device with a router or mainframe system, use the following
command string for best results:
AT&S1&M3*I1&W0Z0

Technical Reference for ZyXEL omni.net series
Making V.120 and X.75 Bundled Calls
Speeds of 128Kbps
BRI ISDN consists of three (2B+D) logical channels. Each B-channel can be used independently
for a dial-up connection running at 56Kbps or 64Kbps (Kbps = Kilo (1000) bits per second).
The two B-channels can be used together for a single data connection to provide 112K (with
In-Band Signaling) or 128K (when Out-of-Band Signaling is used). This is called a "Bundled
Connection".
Identifying your Line Provisioning
For bundled connections, the two B-channels of your ISDN line must be able to handle data circuit
switch connections with unrestricted 64K or 56Kbps line speeds. Two separate data calls will be
established consecutively.
NOTE: V.110 protocol does not support bundled call..
V.120 Bundled Call
A bundled V.120 connection is initiated at the calling site when [ATB20] (B-channel protocol V.120) has been
selected and the channel bundling mode has been enabled by an [AT&J3] command.
The channel bundling command [AT&J3] must be set on both the calling and receiving sides, otherwise a
single channel connection will be made.
AT Command
Description
ATB20<Enter>
Set B-channel protocol to V.120.
AT&J3<Enter>
Enable the omni.net ISDN TA to make a bundled call.
AT&WZ<Enter>
If you want to save the setting.
Table 48. V.120 Bundled Call AT Command (1)
While 'ATJ&3' allows to make a bundle call in both call and answer modes, other bundled call settings are
8-7
Technical Reference for ZyXEL omni.net series
available for more flexibility, as shown below:
AT&J0
Disables B-channel bundling.
AT&J1
Enables B-channel bundling in answer mode only.
AT&J2
Enables B-channel bundling in call mode only.
AT&J3
Enables B-channel bundling in both call and answer modes.
Once this is done, the [ATD] command will generate two consecutive SETUP messages to invoke bundle
initiation.
For the Northern Telecom switch, each BRI phone number can only be called once at any given time. So if
you dial this number, it will report "busy" to any other incoming calls. In order to use two B-channels for
aggregation, we must place two calls with different phone numbers. To do this, separate the two numbers with
a “+” sign after the ATD command, as shown below:
&
ATDI[phone_number_1]+[phone_number_2]<Enter>
The answering ISDN TA determines that the call is a bundle request: when AT&J3 is set, and two consecutive
SETUP messages are received. The two data calls are established as one message. The phone company's
ISDN line splits it off into two messages. That is, the ISDN network treats them as two independent calls.
Finally, the receiving side receives one bundled message into its computer's serial port.
The success of a bundle connection initiation is indicated by the connect message reported to the DTE:
&
CONNECT 115200/V120M 128K/LAPD
Or
&
CONNECT 115200/V120M 128K/LAPD/V42b (with data compression)
Table 49. V.120 Bundled Call AT Command (2)
8-8
Technical Reference for ZyXEL omni.net series
X.75 Bundled Call
A bundle connection is initiated at the calling site by sending two consecutive SETUP messages to the
network. The two SETUP messages are all the same except for the Call Reference values.
[AT&Jn] can be used for bundle configuration as follows:
AT Command
Description
AT&J0
Disables B-channel bundling.
AT&J1
Enables B-channel bundling in answer mode only.
AT&J2
Enables B-channel bundling in call mode only.
AT&J3
Enables B-channel bundling in both call and answer modes.
If channel bundling is enabled, the [ATDIs] command will generate two consecutive SETUP messages to
invoke bundle initiation.
For Northern Telecom ISDN, each BRI destination phone number can only be called once in any time. In order
to use two B channels for aggregation, we must place two calls with different phone numbers. The following
command can be used for this purpose:
&
ATDI[phone_number_1]+[phone_number_2]
If the called site receives two consecutive SETUP messages with the same Calling Party Number and Bearer
Capability then it is deemed as a bundle request. The two data calls are established following normal call
control procedures. That is, the network treats them as two independent calls.
The omni.net uses X.75 Multiple Link Protocol or 'cFos' channel bundling protocol to coordinate the two
B-channels. The former would need an overhead of two octets for each packet. The success of bundle
connection initiation is indicated by the connect message reported to DTE as follows:
&
CONNECT 460800 / X.75M 128K / V42b
If a B-channel is unavailable at either site then the bundle initiation will fall back to single channel connection. In
this case the connect message may be as follows:
&
CONNECT 460800 / X.75 64000 / V42b
Table 50. X.75 Bundled Call

Technical Reference for ZyXEL omni.net series
Dialing Pre-stored Phone Numbers
The 40 phone numbers stored in the NVRAM can also be used to place a bundled call with V.120 or X.75, by
using the [ATDSn] command:
ATDSn
n=0-39
Dial the (n)th phone number twice for both bundle connections.
ATDSn+
n=0-38
Dial the (n)th phone number for the first connection and dial the (n+1)th phone
number for the second connection.
ATDSn+Sm
n=0-39
Dial the (n)th phone number for the first connection and the (m)th phone number for
the second connection.
m=0-39
For example, ATDIS0+S1<Enter> will dial the number stored in location ‘1’, and the number
stored in location ‘2’ for the bundle connection.
Table 51. AT Command for Dialing Pre-stored Phone Numbers
Using V.42bis Data Compression
The following AT commands are used to switch the V.42bis data compression on or off for ISDN
data calls when using X.75 or V.120 protocols:
V.42bis AT Command
Description
AT&K44
Enable V.42bis on V.120 and X.75 ISDN call.
AT&K00
Disable V.42bis on V.120 and X.75 ISDN call.
Table 52. V.42bis AT Command
Bundle Connection with V.42bis Data Compression
If both sites have set [AT&K44] to enable V.42bis negotiation then XID frames will be exchanged
through the main B-channel which corresponds to the call established by the first SETUP message.
Only one data compression channel will be used in bundle connections. That means the
compression is done before packet disassembly and the decompression is done after packet
assembly.
The compression ratio of V.42bis is commonly recognized as up to 4:1 for text files. If the line
speed is 128Kbps, then the DTE speed may reach 512Kbps. This makes the DTE's normal RS-232
8-10
Technical Reference for ZyXEL omni.net series
serial port unsuitable for bundle applications. A special I/O card on the computer side is required in
this situation.
8-11
Technical Reference for ZyXEL omni.net series
Error Correction and Data Compression with V.120
With V.120, the default setting is for LAPD error correction only. No data compression will be
negotiated unless V.42bis is enabled by setting [AT&K44].
With the &K44 setting, the omni.net will try to connect using V.42bis data compression. If the
remote device does not support V.42, then LAPD error correction will be used.
When a connection is made using V.42bis compression, the following connect message will be
displayed:
&
CONNECT 115200/V120 56000/LAPD/V42b.
It takes extra time for the calling ISDN TA to negotiate V.42bis. If you know in advance that the
called site has no V.42bis capability, it is advisable to issue the [AT&K00] command beforehand in
order to get a quick connection.
Since the V.42bis algorithm needs an error-free transmission channel between the compression and
decompression processes, it can only work with a protocol with error control competence. X.75 and
V.120 are such protocols that can be used together with V.42bis data compression. V.110, on the
other hand, is just an R-interface layer 1 adaptation protocol without error-control and is thus
inadequate for V.42bis.
Data Compression with X.75
For X.75, to negotiate compression parameters with the remote ISDN terminal, we exchange XID
frames before the Link Layer is established. The calling site will send an XID frame with V.42bis
request to the called site. If the called site understands this XID's meaning, it will reply to an XID
frame with a V.42bis request. If it is able to execute V.42bis; it will ignore the XID or reply to the
XID frame with a V.42bis reject or empty information field.
The calling site will assume that the remote site is unable to execute V.42bis if it gets no reply for a
period of time after sending the request XID. In this situation, normal connection without data
compression will be established.
8-12
Technical Reference for ZyXEL omni.net series
It takes about 2 seconds for the calling ISDN TA to send XID and wait until time out. If you know
in advance that the called site has no V.42bis capability, it is advisable to issue the AT&K00
command beforehand in order to get a quick connection.
Although not defined in X.75, XID frame is based on the encoding in ISO Standard 8885 and is
used in V.42/V.42bis. In addition to the compression parameters, XID can be used to negotiate the
packet parameters for example as window size or packet size.
Selecting V.120 for European ISDN (DSS1)
With European ISDN, V.120 is an option in the Bearer Capability (BC) information element, which
is a mandatory information element in the SETUP message. Although we can specify V.120 in the
Low-Layer-Compatibility (LLC) information element, some switches just don't deliver the LLC.
Other switches do deliver the LLC, but the V.120 selection will be discarded midway.
If the called ISDN TA does not get any B-channel protocol information from the incoming SETUP
message and the remote device is a ZyXEL ISDN device, the called ISDN TA will be able to
identify the V.120 protocol automatically with the Multi Auto-answer routine. Otherwise, with
other ISDN devices, the handshake will fail.
Security Settings
The omni.net LCD/Plus/D provides security functions used to prevent unauthorized connections.
Your omni.net ISDN TA features two security types with three levels of checks for added
flexibility in the device you are connecting to and the transmission protocols you are using.
Two types of security functions are provided.
#
Type 1 Security is exclusively used when the remote device is ZyXEL ISDN TA.
#
Type 2 Security can be used with remote ISDN TAs of any brand (including ZyXEL ISDN
TAs).
With a Type 1 connection, the dial-in (remote) ZyXEL ISDN TA will send in its supervisor

pre-stored in the password table.
If the password has been matched (in a maximum of 3 tries over a 40 second
time period) with its pre-stored password list, the local omni.net ISDN TA will
check the Calling Party Number (CPN) against the pre-stored number
corresponding to the password. If they are matched, the local TA will choose
either to keep the connection or to disconnect and then call back according to
the setting of bit 6 of S119:
#
S119.6=0 - Disconnect and then call back.
#
S119.6=1 - Keep the connection.
If the CPN does not match with what is stored in the table, the local omni.net
ISDN TA will disconnect the call. If CPN is unavailable in the SETUP message,
the local omni.net will disconnect the call and then call back using the
pre-stored number corresponding to the dial-in password.
Table 54. three levels of security

Technical Reference for ZyXEL omni.net series
Setting and Modifying Passwords
Up to 40 user passwords can be defined using the [AT*Hn] command, where 'n' represents the
index to the entry (n=0-39).
The corresponding 40 callback numbers are defined by [AT&Zn=xxx] command, where 'n'
represents the index to the entry, and 'xxx' represents the assigned callback phone number. Any
character (ASCII 0-127) can be used in the password table. The maximum password length is 8
characters for each entry.
Security functions are only accessible through AT commands in terminal mode.
A supervisory password is required for adding or modifying entries. The default supervisor
password is 'ZyXEL' when the omni.net is shipped from the factory. The supervisory password is
sent to the remote device if Type 1 security is set at the remote end.
Modifying the Supervisory Password
To modify the supervisor password, use [AT*HS].
The system will prompt for the original password and a new password. Then re-enter the new
password for verification. For example:
Password:
********
(Enter current supervisory password)
Password:
********
(Enter new supervisory password)
Verify:
********
OK
8-16
(Enter the new supervisory password again)
Technical Reference for ZyXEL omni.net series
Modifying the User Passwords
Use command [AT*Hn] to modify the "n"th user password (n=0-39). The system will ask you to
enter the supervisory password first and then the user password you want to modify. Use the
command [AT*V] to list the 40 user passwords and the supervisor password on screen for viewing.
Non-password Auto Call Back Function
In addition to the standard modem-like security functions described in the previous section, the
omni.net provides another simpler call back function that does not require any password check.
The Calling Party Number (origination address) will be checked against the 5 pre-stored call-back
numbers before the B-channel is connected. If the CPN is matched with any one of the numbers, the
incoming call will be dropped (without connection, hence without any charge) and the omni.net
will automatically call back the CPN using the matched phone number.
The non-password auto callback function can be controlled using the following AT commands:
#
AT*GC0 - disable the auto call back function (default).
#
AT*GC1 - enable the auto call back function.
The pre-stored numbers can be set using the following [AT*HCn] command:
AT*HCn
Password:
********
(Enter new supervisory password)
Call back phone number:

Fax/Modem Function
Chapter 9
Internal Fax/Modem Function
(for ZyXEL omni.net LCD+M only)
This chapter is designed to describe the internal fax/modem function dedicated to ZyXEL omni.net
LCD+M.
Internal Fax/Modem Basics
The ZyXEL omni.net LCD+M contains a built-in 56K modem that can communicate with other
analog modem through an ISDN line. What’s more, users can send and receive faxes by applying
popular compatible fax packages such as WinFax or Microsoft Fax.
Modem Standards and Speeds
The internal modem supports the following standards and speeds, which are recommended by
ITU-T or ITU-TSS (International Telecommunications Union - Telecommunications
Standardization Sector).

Notes
Table 55. Modem Standards and Speeds
MNP Protocols
MNP (Microcom Network Protocol) is a set of protocols first introduced by Microcom, Inc., and
alter used by many modem manufacturers. It consists of many classes. Class 1 to 4 are for error
correction, and class 5 is for data compression. MNP Class 1 and 2 are obsolete. Normally Class 4
is used for error correction and it uses Class 3 internally.
MNP Class 5 is data compression protocol with a maximum efficiency of 2 to 1. MNP-5 is used
with MNP-4 for error correction.
Xmodem, Ymodem, and Zmodem
These are file transfer protocols. They do error checking and ensure data integrity of the file
transferred. Some variations of these protocols also appear, like Xmodem-1k, Ymodem-G, etc.
The “G” types of protocols do not include error checking. They allow very high throughput rates,
but can be safely used only when the modems use MNP4 or V.42 error protocols and there is no
speed overrun on the computer’s serial port.
Whenever possible, we recommend the use of Zmodem for added security and high flexibility.
Consult your communications program manual for more information on transfer protocols.
9-2
Fax and Facsimile
Fax is the abbreviation for facsimile. There are four major parts in a normal facsimile machine, the
scanner, encoding and decoding device, modem, and printer. Before a page can be sent, it is first
scanned, the bit-mapped data is encoded with data compression, and then it is transmitted across the
phone line by an internal modem module. The remote facsimile receives the data with its internal
modem, decodes it back to bit-mapped image data and prints it on paper.
Modem as a fax
Modems can also be designed to include a fax transmitting and receiving function similar to a fax
card. Since the modem’s interface with the computer is the standard serial RS-232 interface, this
interface is used for both modem and fax operations. Since the data throughput on a serial RS-232
interface is limited, only compressed fax image data should be carried through this serial interface.
Fax image coding and decoding must be done in the computer. Modem/Fax, also called faxmodem,
can be either an external stand-alone unit or a plug-in card. External stand-alone units can be
connected to any computer with a standard RS-232 serial port.
EIA Class 1 Fax Commands
The EIA Class 1 fax commands are a set of AT fax commands defined by
EIA/TIA(Telecommunications Industry Association) for controlling faxmodems from a computer
through the serial RS-232 interface. Faxmodems and fax software supporting this standard will
work together. Class 1 commands control the details of how the modem does on-line negotiation.
The Class 1 command set is also called the TIA-578 standard.
Constriction of Using Internal Fax/Modem and Phone2
The internal fax/modem is using the same circuit of POTS port phone2, that is, when POTS port
phone2 is in use, you can not dial out/in a modem call. On the other side, when internal fax/modem
is in use, if you pick up phone2, you will hear the noise of modem carrier or handshaking.
9-3
Technical Reference for ZyXEL omni.net series
Dialing Out for Internal Fax/Modem
Using the “M” command following the “ATD” will tell your omni.net LCD+M to automatically
switch calls to the internal fax/modem once dialing is complete.
Type: ATDM17146930762<enter>
Manually Switching Communication Modes
The manual switching functions will only be necessary if your communication software does not
allow you to change your dial-up string.
Conventional dialing commands: ATD, ATDT and ATDP, used by most existing communication
software, can be mapped onto one of the new dialing commands according to the AT&O setting as
follows:
AT Command
Dial string it will map to
AT&O0
ATD, ATDT and ATDP are the same as ATDM
AT&O1
Auto-selection of 64kbps and 3.1 kHz on outgoing calls
AT&O2
ATD, ATDT and ATDP are the same as ATDI
AT&O3
ATD, ATDT and ATDP are the same as ATDA
Table 56. AT Command for Conventional dialing commands
The factory default is AT&O2. This means the modem will select ISDN data mode when you do
not specify which communication mode to use in your dial command (i.e. ATD or ATDT).
ATDMs
This command directs the modem to go on-line, dial according to the string entered and attempt to
establish a connection.
If +FCLASS=0 is selected, the modem will behave as a data modem and will attempt to connect to
another data modem. The modem will have up to the period of time specified by register S7 to wait
for a connect. If this time expires before the modem can connect, the modem will go on-hook with
the NO CARRIER response. This command will be aborted in progress upon receipt of any DTE
9-4
character before completion of the handshake.
If +FCLASS=1 is selected, the modem will behave as a facsimile modem and attempt to connect to
a facsimile machine. This command will be aborted upon receipt of any DTE character if the
modem has not finished dialing. In this case, the modem will go on-hook and return to command
mode after displaying the NO CARRIER message.
Dial Modifiers. The valid dial string parameters are described below. Punctuation characters may
be used for clarity, with parentheses, hyphen, and spaces being ignored.
0-9 DTMF digits 0 to 9.

Incoming Calls for internal Fax/modem
Answering a Call Using MSN
AT&ZI6=s Assign the phone number to a POTS port, Phone 2 and internal fax/modem when
AT&L1 was set. (For more information, please refer to Answering a Call Using MSN on chapter 4)
Allow Internal Fax/Modem to Answer Incoming Analog Calls.
The factory default will not allow the internal fax/modem to answer an incoming call (AT&L0).
Command AT&L1 will make an incoming analog call not only to phone2 but also to the internal
fax/modem.
9-5
Technical Reference for ZyXEL omni.net series
When AT&L1 is set, an incoming analog call to phone2 will also report a ‘RING’ message to the
DTE. You can answer an incoming analog call to the internal fax/modem by the command ‘ATA’.
If the register S1 is not zero, the internal modem will automatically answer an incoming analog call
when the Ring counter reaches the register S1 value. However, you can pick up phone2 (or phone1
when Global Call is enabled) to answer this incoming analog call.
LCD Panel When Internal Fax/Modem Operation
When the modem (or fax) calls out, the LCD panel will display the destination number
of the modem (or fax) to dial to. When using the internal fax/modem to answer an
incoming analog call, the LCD panel will display the calling party number of the modem
(or fax) the call came from. After the modem (or fax) call has finished, the LCD panel will
record the modem (or fax) call in the dial in (or out) log.

Fax Operation
The ZyXEL omni.net LCD+M supports the Group 3 sending and receiving facsimile function. You
must connect the modem to a computer, usually a PC. The computer is the input/output device for
the fax function. The interface between the modem and the computer is the normal RS-232 serial
connection. The modem uses the same interface for both data and fax applications. In fax operation,
it performs protocol handshaking and image data transfer, and the computer does the job of image
data creation, capturing, conversion, compression, decompression, retrieving, and storing. You can
send and receive fax by applying popular compatible fax packages such as Winfax or Microsoft
Fax.
9-7
Technical Reference for ZyXEL omni.net series
The fax may achieve a14400 bps transmission speed. The character format is 8 bit data, no parity,
and 1 stop bit. Start and stop elements are removed from the transmit data and added to the receive
data. Both transmit and receive data are buffered. Flow control using XON/XOFF (DC1/DC3) or
RTS/CTS is provided.
Fax Command Sets
Besides the AT commands supported by omni.net LCD, there are additional AT commands for
internal fax/modem usage for a control speaker (ATMn and ATLn), data compression (AT&Kn),
modem dial out (ATDMs), fax command sets (EIA Class 1 fax commands), etc.
The omni.net LCD+M internal modem supports Class 1 command set for the fax function. The
Class 1 protocol uses the modem to transmit the fax data only. The connected computer handles the
complete organizational overhead for this protocol. The available Class 1 commands are listed first
in this chapter.

10-1
Technical Reference for ZyXEL omni.net series
Power-on Self-test
At each power-up or after reset command from the panel, the omni.net will test the ROM code
checksum, system RAM memory, EEPROM, digital circuits and analog circuit calibrations.
The LNK LED will light up for half a second to indicate the success of the TA's power on self-test.
After completing a successful self-test, the LNK LED will become the normal physical layer (layer
1) active indicator.
ISDN Loopback Test (AT&T9)
The [AT&T9] command will invoke an ISDN loopback test connection. The loopback point is in
the S/T interface chip (Siemens 2086 chip). This loopback checks almost every part of the omni.net
ISDN TA and RS-232 cable, except for the passive front-end of the ISDN S/T interface.
During ISDN loopback test, data from the terminal or computer is sent through the DTE interface to
the omni.net's transmitter and is packaged to the proper frame format according to the B-channel
protocol selected. Then the test data-packet are loop-backed to the receiver, unpacked, and sent
through the DTE interface back to the terminal or computer's screen. The screen should show the
data you have sent to the ISDN TA.
Loopback with Self-Test (AT&T10)
The [AT&T10] command will invoke an ISDN loopback connection with self-test. The data is
generated by the omni.net and goes through the same path as with the above Loopback Test. The
data pattern is printable ASCII characters. You can see the result on the screen. The loop-backed
data is compared with the transmitted data. Should an error occur, the LNK LED will start to flash.
Sending any character through the DTE interface to the ISDN TA will discontinue the test.
B1/B2 Loopback with Self-Test (AT&T11)
The [AT&T11] string commands testing for the readiness of your ISDN line which uses one
B-channel (B1) to place a call and the other B-channel (B2) to receive the call. Follow these
instructions to make your test call:

Resetting Your omni.net
If you have modified the setting and cannot get your ISDN back on-line (the unit is locking up), you
need to reset your omni.net. Also, you can follow the reset procedure to help you reset the omni.net
back to the factory set default-state.
To reset your omni.net Plus/D, hold the DATA/VOICE button pressed down while turning the unit
ON; to reset your omni.net LCD/LCD+M, hold any key in LCD panel,, and keep holding down the
switch for 5 seconds after the power switch is turned ON, then release the switch. The omni.net will
reset itself back to the factory defined setting, and it will also run a continuous loop-back self-test.
Printable characters will show on the terminal screen (if connected). Finally, toggle the power OFF
and ON again.
Other than the mechanical reset described above, you can use the terminal program to perform
software and hardware reset by issuing the following AT commands:
omni.net Reset
AT Commands
Description
ATSWR
Software reset. After ATSWR is issued, the omni.net restarts the system.
ATHWR
Hardware reset. After ATHWR is issued, the omni.net clears the NVRAM, loads factory
default S parameters, and restarts the system.
Note: These two reset commands are protected by key S38.2=1. This implies that you must set [S38.2=1]
before issuing a ATSWR or ATHWR command.
Table 62. omni.net Reset AT Commands
Using the Embedded Protocol Analyzer (EPA)
The embedded protocol analyzer (EPA) records and analyzes various protocols on the B-channel,
10-4
Technical Reference for ZyXEL omni.net series
D-channel and DTE-DCE interface. The EPA is designed for hobbyists as well as users with
technical backgrounds. The EPA enables you to examine messages exchanged between your ISDN
TA and the Central Exchange office when making an ISDN call. You can review the packets sent
or received through the B-channel (for X.75 or V.120) to or from the remote site. AT commands
issued from an application software program can also be checked. This will help you understand
their causal relationship with other events.
In addition to its tutorial purpose, the EPA is very useful for diagnostics. If you have compatibility
problems with your Central Exchange or with another ISDN TA device at a remote site, the EPA
will be your first aid resource. According to the EPA analysis, you may decide to fix the problem
yourself (for example, modify the configuration and try again) or log the analyzed results as a file (a
very comprehensive bug report), and then send it to ZyXEL Technical Support department.
Capturing the Protocol Data
The data captured by the EPA can be classified into three categories:
!
B-channel user data protocols
!
D-channel signaling protocols
!
DTE-DCE protocols
The B-channel user data protocols include X.75 and V.120. Only the layer-2 header (addresses and
control bytes) and layer-3 header are captured. Since X.75 may be used with various layer-3
protocols (for example, T.70, T.90, and ISO8208), only the first 8 octets of the information field are
recorded as the layer-3 header, then displayed in raw data form. ZyXEL Technical Support
department will carry out the analysis of the protocol data.
The D-channel signaling protocols include layer-2 and layer-3 call control protocols. Frames and
messages exchanged via the D-channel are all recorded for further analysis. These data messages
are essential to understanding interactive operations between an ISDN TA and the ISDN network.
They contain the compatibility information for the ISDN TA and your Central Exchange.
The DTE-DCE protocols (at the R reference point according to the ISDN nomenclature) include
the AT commands/responses as well as the CAPI internal interface. The CAPI internal interface is
10-5
Technical Reference for ZyXEL omni.net series
used with the ZyXEL CAPI driver. The ZyXEL CAPI driver communicates with the ISDN TA
through this internal interface. It is not recommended that users get involved in this internal
interface. The AT commands/responses, on the other hand, are in a standard user interface. An
analysis of these commands and responses might prove very informative. All messages captured by
the EPA are tagged with a time stamp according to a free running timer that starts at the beginning
of data capture. The resolution of this timing information is in 10ms intervals.
The following commands determine the kind of protocol data captured by the (Embedded Protocol
Analyzer) EPA:

Chapter 11
Firmware Upgrade
This chapter describes how to upgrade the flash EPROM firmware of your omni.net when a new
version is available.
Upgrading with Flash EPROM
Your omni.net ISDN TA employs a flash EEPROM (Electronic Erasable Programmable Read
Only Memory) that lets you conveniently update firmware and program the ISDN TA with new
features and enhanced functions.
If you use a Windows operating system, run the ZyXEL ISDN Configuration Manager to upgrade
new firmware. For other Operating Systems, use a terminal program that supports the X-modem
protocol.
Obtain the new firmware from ZyXEL's BBS, WWW, or FTP site. See Contacting ZyXEL for
more information. The firmware is distributed with the file name (your model) d.vvv, where the
extension 'vvv' denotes the version of this firmware. The modifier 'd' in the filename has the
following definitions:
!
d = E - European ISDN (DSS1), also used in most other countries including Asian
countries.
!
d = A - American ISDN (AT&T 5ESS, Northern Telecom DMS-100, or National
ISDN-1, the active D-channel protocol can be chosen by an AT command).
11-1
Technical Reference for ZyXEL omni.net series
NOTE: The American firmware version supports both the S/T
interface and U interface models. During the power-on test, it checks
the hardware configuration and follows the initialization procedures
of the specific interface.
Follow these steps to upgrade you omni.net with flash EPROM, by using a communications
program:
Step 1. Make sure your omni.net has the power turned ON.
Step 2. Start any communications program on your computer that supports the Xmodem
protocol, and type:
!
ATUPX<Enter>
!
omni.net responds: You have chosen Xmodem (128 octets of
data with checksum) protocol to update your TA. Data
in Flash ROM will be erased !!!
Are you sure (Y/N) ?
Step 3. Press 'Y'. The following message then appears:
Start programming, please upload.
Step 4. Use the Xmodem protocol to upload the file ONETd.vvv to your ISDN TA. This
step updates the omni.net's flash EPROM with the new firmware. When installation
is complete, the omni.net will restart automatically.
Kernel Mode
In the unlikely event that your omni.net fails to respond to AT commands after upgrading the flash
EPROM, follow the procedure below:
1. Power on the omni.net. The reset will prompt the omni.net to check the integrity of the codes in
the flash EPROM.
2. If proper valid firmware can not be verified, the omni.net will initiate Kernel Mode. Once it is
in Kernel mode, you can issue limited AT commands. From this point, you can start from Step
11-2

AT Command Set Reference
Operation Modes of the DTE Interface
There are two operation modes for the DTE interface:
!
Simplex mode - used for conventional AT Command operation.
!
Multiplex mode - used as an internal interface for ZyXEL CAPI drivers.
Simplex mode
In simplex mode, the omni.net is used just like an ordinary ISDN TA. The DTE interface will be
either in command state or in data state. At the most, only one data connection session is possible at
any time.
A number of different AT Commands can be used to invoke various functions. The simplex mode
is designed for AT Command users. The guides and descriptions throughout the rest of this manual,
if not otherwise specified, are applicable to this mode. The power-on default of the DTE interface is
in simplex mode as well.
Multiplex mode
The multiplex mode is designed for ZyXEL CAPI drivers. It can also be used by third parties to
develop various drivers on different platforms for public domain or for commercial purposes.
A-1
Technical Reference for ZyXEL omni.net series
The commands or data are packaged. Each packet has its own destination address. All the DTE
channels can be accessed individually by way of multiplexing.
AT Commands Description
An AT Command is a command in asynchronous data format issued by the computer to the ISDN
TA through the asynchronous computer-modem interface. AT Commands control the ISDN TA
behavior and actions. To send an AT Command from a computer to the omni.net, you must run a
communication software program and the omni.net must be in command state.
Exceptions to the above requirement are [A/, A>, and +++.] These commands are neither preceded
by the prefix AT, nor followed by any other character:
!
A/ - re-executes the last command once.
!
A> - re-executes the last command once. Also used to repeat the last call up to 9 times
until aborted by pressing down any key on the keyboard or front panel or until a
successful connection with a remote ISDN TA has been made.
!
+++ - is the escape sequence code that is entered in data state to return the ISDN TA to
command state. The omni.net will accept AT commands only while it is in command
state.
AT Commands Prefix (AT)
All other AT Commands require the command prefix [AT]. The prefix may be typed in either
upper 'AT' or lower case 'at'.
NOTE: Do not use a combination of upper and lower cases in the
prefix.
The following tables list all of the AT commands supported by the omni.net LCD/Plus/D. An
asterisk (*) following a command option or value indicates that it is a default setting when the
omni.net is shipped.

Appendix B
Status Registers & Result Codes
S-registers (Status Registers) contain values that determine and reflect how your omni.net Terminal
Adapter (TA) operates and executes commands. You can read the values and change them, using
either terminal commands or the TA's panel controls with the same results.
Every user profile corresponds to a separate set of S-register values, but when we mention
S-registers, we are referring to the ones that correspond to the active profile. If you want to read or
change the values in a profile that is currently inactive, you will first have to recall that profile to
make it active.
At the time of this edition of the manual, the omni.net is equipped with 125 S-registers, from S0 to
S124. S0 to S11 are standard AT S-registers, and S12 to S124 are mostly bit-map configured.
Changes in the bit-map configuration can have the same effect as issuing AT Commands. However,
it is recommended to use equivalent AT Commands.
Viewing and Setting S-Registers
There are several AT Commands that are used to view the values stored in the S-registers.
Viewing S-registers
To display the value stored in S-register 'r' use the following AT command:
#
ATSr?
B-1
Technical Reference for ZyXEL omni.net series
To view all of the S-register settings use the '&Vn' AT command:
#
AT&Vn
The following table summarizes the S-register viewing commands.
S-register Viewing AT
Commands
Description
ATSr
r=0-124
Display the value stored in S-register 'r'.
AT&Vn
n=0-7
View all of the S-register settings.
&V0
View S-register settings for current active profile.
&V1 to &V4
View settings for user profile number (n-1).
&V5
View the factory set default settings.
&V6
View the POTS port 1 setting, Phone 1. (for omni.net LCD/Plus).
&V7
View the POTS port 2 setting, Phone 2. (for omni.net LCD/Plus).
Note: The S-register values may be displayed in either Decimal or Hexadecimal format when using the
preceding commands. Bit 3 of S-register 84 sets which numbering system is used for display.
ATS84b3=0
Display in decimal format.
ATS84b3=1
Display in Hex format.
For example, to display the value of bit 'm' of S-register 'r', use:
!
ATSrbm?
Table 72. S-register Viewing AT Commands
Setting S-registers
In order to change the value in S-register 'r' to value 'n', use:
!
ATSr=n (range 0-255)
In order to change the value in a specific bit 'm' of S-register 'r', use:
!
ATSrbm=n (range 0-1)
In both commands, 'n' is a decimal number in the given range. While the first command modifies all
B-2
Technical Reference for ZyXEL omni.net series
bits in the S-register simultaneously, the second command lets you change bit 'm' without affecting
other bits in this S-register. When using ATSr=n, you need to do a conversion to or from the binary
number to find out which bits you manipulate.
For example, if you want to set S38 bit 3 to 1 for a specific application, you may either use the
straight-forward command ATS38b3=1 or use the following ATS38=n command, as explained in
the following example:
1.
Read the value from S38 using ATS38?
NOTE: The values used in the example below differ from the actual
values in the S-register and are used for demonstration purposes only.

S-Register Descriptions
In most bit-mapped S-registers, the default bit value is 0 (which is the normal situation), only the
non-default situation is described. Some reserved bits are for factory use and the user should not
change them.
Values followed by an asterisk (*) are the factory set default settings.
The following sections provide a description for each S-register.
